posterior sector of right lobe of liver

The posterior sector of the right hepatic lobe is a major anatomical division supplied by the posterior segmental hepatic artery and drained by the posterior sectoral vein.

Located in the right portion of the liver, the posterior sector comprises segments VI and VII on the inferior and superior surfaces respectively.

The posterior sector performs hepatic metabolic, synthetic, and biliary functions as an integrated unit with the anterior sector of the right lobe.

The sector receives blood from the posterior branch of the right hepatic artery and portal vein, and drains through the right hepatic vein to the inferior vena cava.

Distinction between anterior and posterior sectors is essential for planning partial hepatectomy, liver transplantation, and interventional radiology procedures.
